Tolerance compatibility issues cost the construction industry millions upon millions of dollars a year. The ACI 117 tolerance committee has attacked this issue head-on by developing “A Guide for Tolerance Compatibility in Concrete Construction”. The document, due to be published in August, assists the architect, engineer and contractor by identifying industry standard tolerances and presenting recommendations for mitigating tolerance conflicts related to the interface between concrete and the following work: embedded items, elevator cores and hoistways, openings in slabs and walls, manufactured couplers and splicing systems for reinforcing bars, stairs, cladding systems, infill wall systems, surface accessibility components, finish floor coverings, and expansion joints.
